【摘要】：切削力是高速切削过程中重要物理量之一,直接影响到加工质量和刀具寿命。文章采用中心复合响应曲面法建立了碳纤维增强复合材料(carbon fiber reinforced polymer,CFRP)高速铣削过程切削力模型,并用方差分析对模型及回归系数进行了显著性检验,分析了主轴转速、每齿进给和切削深度对切削力的影响规律,为高速铣削过程中切削参数的选择及切削力的控制提供了试验依据。试验结果表明:该模型能较好地预测切削力,切削深度和每齿进给对切削力的影响较大,切削力随着切削深度或每齿进给的增大而增大,主轴转速则对切削力影响不是很大。
[Abstract]:Cutting force is one of the important physical quantities in high speed cutting process, which directly affects machining quality and tool life. In this paper, the cutting force model of high speed milling process of carbon fiber reinforced composite material (carbon fiber reinforced polymer,CFRP) is established by using the central composite response surface method. The significance of the model and regression coefficient is tested by variance analysis, and the rotation speed of spindle is analyzed. The influence of feed and cutting depth of each tooth on cutting force provides experimental basis for the selection of cutting parameters and the control of cutting force during high speed milling. The experimental results show that the model can predict the cutting force, the depth of cutting and the feed per tooth have a great influence on the cutting force. The cutting force increases with the increase of the cutting depth or the feed per tooth, while the spindle speed has little effect on the cutting force.
